the end of the manual) as a guideline to cut a hole in the dash to the specified dimensions. Drill
holes where indicated on the template for the mounting screws.

Mounting the Unit
1. Place the backside of the display through the opening in the dash.
2. Use the four screws to line up the unit with the drilled holes.
3. Push the unit through the opening and screws through the drilled holes until the back of
the case is flush.
4. Use the Nylock nuts provided to tighten unit to the dash. Use the appropriate wrench or
socket to tighten. Torque lock nuts to 8-10 inch pounds.
Flush Mounting the Dash
1. Cut the dash to allow for the display without bezel. Make sure enough material remains
to properly secure the display within the dash. Torque the 6-32 Nylock nuts to 5-inch
pounds.
2. Place the display behind dash and line up the four mounting holes on the display with
the holes in dash.
3. Install four bolts and tighten nuts.
